This application is based on the Chinese patent application with the application date of "2021-10-29", the application number of "202111275847.7", and the invention titled "Lightweight and large-load commercial vehicle stabilizer bar suspension rod assembly and its preparation method" , and claim its priority, the full text of the Chinese patent application is hereby incorporated into this application as a part of this application.

【Technical field】

The invention belongs to the technical field of lightweight design of automobiles, and relates to a stabilizer bar suspender assembly and a preparation method thereof, in particular to a light-weight and large-load commercial vehicle stabilizer bar suspender assembly and a preparation method thereof.

【Background technique】

With the gradual establishment and implementation of national energy conservation and emission reduction, green environmental protection policies and regulations, and the acceleration of the construction of a resource-saving and environment-friendly society, automobile energy conservation has become a key research topic in the development of the automobile industry. Studies have shown that reducing the weight of the car itself is one of the effective measures to improve the fuel economy of the car and reduce the CO2 emission of the car.

The stabilizer bar is an auxiliary elastic element in the car suspension, which is used to prevent the body from excessive lateral roll when turning, and the stabilizer bar hanger is used to connect the suspension arm and the stabilizer bar. At present, the stabilizer bar and suspender are usually designed with metal parts as a whole, which requires many manufacturing processes and heavy weight, which cannot meet the needs of light weight.

The Chinese patent document "A Forged Stabilizer Suspender and Support Assembly and Vehicle Using the Assembly" with the publication number CN213007481U discloses a forged stabilizer suspender, which does not have a significant lightweight effect . The Chinese patent document "A Lightweight Structured Truck Stabilizer Suspender" with the publication number CN211844016U discloses a lightweight stabilizer suspension pole, but it is a curved pole structure, applicable to fewer models, and cannot be interchanged in large quantities . The Chinese patent document "A Lightweight and Environmentally Friendly Automotive Stabilizer Link Assembly" with publication number CN207433181U discloses an injection-molded stabilizer link. One end of the link is fitted with a rubber-metal bushing, and the other One end is integrally injection-molded with a connecting rod main body. When installing this structure, it is not convenient to change the structure of the opponent stabilizer bar. Moreover, the connecting rod structure disclosed in this technology adopts the traditional injection molding process, which cannot meet the application scenarios of large loads.

To sum up, it can be seen that the existing stabilizer bar and boom assembly cannot have the dual characteristics of meeting the heavy load service conditions of commercial vehicles and significant lightweight effects at the same time. Therefore, it is necessary to develop a new stabilizer bar boom assembly.

Wrap the fiber between the first bush (4) and the adjacent fourth bush (10), between two adjacent fourth bushes (10), the second bush (8) and Between the adjacent fourth bushes (10), between the third bushes (9) and the adjacent fourth bushes (10), after the winding is completed, a reinforcement body (3) and bushings are formed. Intermediate;

S2. Put the intermediate into a mold of expected shape, vacuumize at room temperature, and then pour a thermosetting resin composite material at a temperature of 23°C to 40°C. After the composite material is completely impregnated with the intermediate, stop pouring and heat the mold to 80°C-90°C, curing for 2h-3h and demoulding, to obtain a lightweight and heavy-duty commercial vehicle stabilizer bar and suspender assembly.
The method for preparing a light-weight and heavy-duty commercial vehicle stabilizer bar and suspender assembly according to claim 10, wherein in step S1, the fibers are wrapped with a silane coupling with a hydrophilic functional group before being wound. and/or, in step S2, the vacuum is evacuated until the degree of vacuum is below -0.1MPa, and the pressure drop is met after holding the pressure for 10 minutes before pouring, and the thermosetting resin composite material is epoxy-containing The thermosetting resin composite material of resin or the thermosetting resin composite material containing polyurethane resin, the thermosetting resin composite material is subjected to defoaming treatment before pouring.
